    摘要： The peak value of an initial load in a self-fracture occurring during transition to a stable sequential fracture mode is controlled, and a desired amount of absorbed energy is ensured. An impact-absorbing member (3) is formed of reinforcing fiber and resin and includes a plurality of fiber-reinforced resin layers that absorb an impact through a self-fracture when subjected to the impact. Reinforcing fibers in at least one fiber-reinforced resin layer (5) at a leading portion (3a) extend in a direction falling within the range of 90°±45° with respect to an energy-absorption axis direction, whereas reinforcing fibers (7) in the same fiber-reinforced resin layer in a impact-absorbing-member main body (3b) excluding the leading portion (3a) extend in a direction falling within the range of 0°±45° with respect to the energy-absorption axis direction.

    摘要： A nondestructive inspection apparatus according to the present invention has a transmission-side probe configured to emit a first ultrasonic wave toward a test-target fluid, a plate through which a Lamb wave generated by the first ultrasonic wave is propagated when the first ultrasonic wave is propagated, and a reception-side probe configured to measure intensity of a second ultrasonic wave which is emitted from the plate and propagates through the test-target fluid. At this time, the nondestructive inspection apparatus can inspect the test-target fluid without bringing the transmission-side probe configured to emit the first ultrasonic wave and the reception-side probe configured to measure the second ultrasonic wave into contact with the test-target fluid.
